This is still happening in WP 4.6.1 and I do not have YOAST installed.
I’m using an Elegant Themes “eVid” theme with JetPack activated.
Interesting. I’m getting exactly the same issue but without YOAST installed on this particular site (yet!)
Thank you very much songdogtech.
I obviously need to improve my searching skills!
Let me know if anyone needs any further inforamtion to help with this.
Cheers.
